Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573482, here are decompositions:

19 + 31573463 = 31573482
89 + 31573393 = 31573482
223 + 31573259 = 31573482
229 + 31573253 = 31573482
271 + 31573211 = 31573482
293 + 31573189 = 31573482
331 + 31573151 = 31573482
349 + 31573133 = 31573482

Showing the first eight; more decompositions exist.
